Question

Speed and travel time are inversely related, the faster you go, the less time it takes

to get to your destination. If it takes 20 minutes to get to school when you go 30 mph,
how long will it take to get to school if you travel 45 mph? (hint: speed=k/time)

Answer 1

Explanation:

speed = distance/time

however speed is a compound measure

distance to school = speed x time

= 30mph x 1/3hr

= 10m

time = 10m / 45mph

= 13.3 (recurring)

= 13 mins
