ONE FOR MANY

ONE FOR MANY

LEARNING MANY MATHEMATICAL ASPECTS USING ONE PROBLEM

F 1 (TIME)

There is a circular path around a sports field. Sonia takes 18 minutes to drive one round of the field, while Ravi takes 12 minutes for the same. Suppose they both start at the same point and at the same time, and go in the same direction. After how many minutes will they meet again at the starting point? (NCERT Textbook class 10 Ex 1.2)

Multiple Choice

TIME TAKEN FOR RE-UNION!!

F1 (THE NUMBER)

There is a circular path around a sports field. Sonia takes 18 minutes to drive one round of the field, while Ravi takes 12 minutes for the same. Suppose they both start at the same point and at the same time, and go in the same direction. how many circular laps will sonia take to meet ravi again at starting point?

Multiple Choice

• LCM

• HCF

• MULTIPLE

• UNITARY METHOD

F1 (THE PROGRESSION)

There is a circular path around a sports field. Sonia takes 18 minutes to drive one round of the field, while Ravi takes 12 minutes for the same. Suppose they both start at the same point and at the same time, and go in the same direction. After completing first lap Sonia realized that she is going slower, so she increased her speed such that it take same time to complete one round as ravi. Find the time taken by sonia to complete 7th round with new speed?

Multiple Choice

7^th Round

• 1 hour

• 1 hour 30 min

• 2 hour

• 2 hour 30 min

what is the method/aspect of mathematics YOU used to find answer.

• unitary method

• Arithmetic Progression

• Linear Equation

• i don't know just got the answer from my mind!

F1............ (The circular Track!!)

There is a circular path around a sports field. Sonia takes 18 minutes to drive one round of the field, while Ravi takes 12 minutes for the same. Suppose they both start at the same point and at the same time, and go in the same direction. After 3 min, Ravi covered a distance 250m of the track from starting point. Find the total length of the track?

Multiple Choice

Circumference of circular track!!

• 1 km

• 2 km

• 3 km

• 4 km

what is the method/aspect of mathematics YOU used to find answer.

• unitary method

• areas And Circumference of circle

• speed time distance formula

• Arithmetic progression
