Finding Distance, Rate, and Time

What is the distance formula?

• D=R/T

• D=T/R

• D=R*T

• Uhhh...

What is the rate formula?

• R=D/T

• R=D*T

• R=T/D

• We did not learn this

What is the time formula?

• T=R/D

• T=D/R

• T=D*R

• T=minutes

If Courtney drove at a constant speed of 65 miles per hour for 5.5 hours, how many total miles did he drive?

• 357.5 miles

• 11.8 miles per hour

• 350 miles

Sarah walked at a constant speed of 20 blocks per hour. If she walked for 30 minutes how many blocks did she walk?

• 60 blocks

• 15 blocks

• 10 blocks

Harry ran for 2 hours. If he ran a total of 6 miles, what was his speed? (think miles per hour)

• 2 miles per hour

• 12 miles per hour

• 3 miles per hour

Ellie drove her car at a constant speed of 70 miles per hour. If she drives for 120 minutes, how many miles will she drive?

• 600 miles

• 2.4 miles

• 140 miles

Maggie lives 15 km away from her friend. If she walks at a constant speed of 5 km per hour, how long will it take her to get to her friends house?

• 2 hours

• 3 hours

• 2.5 hours

• 3 km/hour

How do you calculate speed? (rate)

• divide the time by the distance (time/distance)

• Divide the distance by the time (distance/time)

• multiply the distance by the time (distance x time)

• multiply the speed by the time (speed x time)

How do you calculate distance?

• Divide the speed by the time (speed/time)

• Multiply the rate of speed by the time (rate x time)

• divide the rate by the distance
