In this diagram

If 10X = Y, then Y =

• 105 degrees

• 200 degrees

• 180 degrees

• 105 degrees

• 220 degrees

Answer explanation

Sum of all angles = 360.

So, 4X + Y + 80 = 360.

4X + 10X = 360 - 80.

14X = 280.

This means X = 20.

Hence, Y = 10 x 20 = 200.

Adam drives at 60 kilometers per hour for a part of the route, then accelerates to 100 kilometers per hour for the rest of the way.

The trip takes him eight hours. The trip is 700km total.

How many hours has he been driving at 60 kmph?

• 2 hrs 40 min

• 4 hrs 40 min

• 3 hrs 12min

• 2 hrs 30 min

• 3 hrs 20 min

Answer explanation

If Ron was driving at 60 km/h for 'h' hours, then distance covered in that time = 60h km.

He would have, therefore, travelled the balance (8 – h) hours at 100 kmph.

Distance covered in this (8 – h) hours = (8 − h) × 100 = (800 – 100h) km.

The total distance travelled = 60h + 800 – 100h = 700.

h = 2.5
