Question

A hare and a tortoise compete in a race over a course 1.50 km long. The tortoise crawls straight and steadily at its maximum speed of 0.290 m/s toward the finish line. The hare runs at its maximum speed of 7.55 m/s toward the goal for 1.200 km and then stops to tease the tortoise. How close to the goal can the hare let the tortoise approach before resuming the race, which the tortoise wins in a photo finish? Assume that, when moving, both animals move steadily at their respective maximum speeds.

Answer 1

The answer is Th=39s and X= 11m

Explanation:

The necessary time for the hare to complete the 0.290 km

Th=xf-xi/vh = 1500m-1200m÷7.55m/s=39s

then the tortoise must be x distance from finish line so that the hare continues the race

x=vt

x= 0.290m/s(39s)=11,3m
