Question

Canada Olympic Park features sports training and entertainment facilities.The monster Zip line produces average speed of 120 kilometers per hour. A smaller line produces speeds represented by the function d=50h where d is the distance in kilometers after h hours. How much farther could you travel on the Monster Zip line in 0.25 hours

The answers I can choose are

18km

16km

20km

17.5km

​

Answer 1

17.5 Km

Explanation:

In Monstor zip line, it's 120 km /hour

so in 0.25 hours, it's 0.25 * 120 = 30 Km

in another small

d = 50*h

= 50*0.25

= 12.5 km

so you travel (30-12.5)km farther on the monster zip line = 17.5 Km
