Question

A friend calls you and asks you to meet at the park 2 mi away in 25 min. You set off on your skateboard after the call. At what speeds (in miles per minute ) can you ride your skateboard to be at the park in at most 25 min? How are the distance you travel, your speed, and time related? How can an inequality help you solve the problem? How can the model below help you solve the problem?

Answer 1

speed greater than 0.08 mi/min

Explanation:

given data

distance = 2 mi

time = 25 min

to find out

the distance you travel and your speed and time related

solution

we know that distance is

distance = speed × time ...............1

so at park at most 25 min

so we need time =
`(distanec)/(speed) \leq 25`

so here

we know

`(2)/(25) \leq speed`

so

`0.08 \leq speed`

so we can say that he need to run at speed greater than 0.08 mi/min
