The time needed to travel a certain distance varies inversely with the rate of speed. If it takes 8 hours to travel a certain distance at 36 miles per hour, how long will it take to travel the same distance at 60 miles per hour?

———hours ?

How long will it take to travel the same distance is 4.8 hours

Using this formula

t=k/r

Where:

t represent Time

k represent the constant of variation

r represent speed

Let plug in the formula

Time=8hours×36 miles per hour/60 miles per hour

Time=288 miles/60 miles per hour

Time=4.8 hours

Inconclusion How long will it take to travel the same distance is 4.8 hours.

4.8

Step-by-step explanation:

Speed = distance/time

36 = distance/8

Distance = 36×8

= 288

60 = 288/time

time = 288/60

= 4.8

-12 > a

step-by-step explanation:

-11 > 1 + a

subtract 1 from each side

-11 -1> 1 -1+ a

-12 > a
