Please help! It’s not too hard! Will mark brainliest!
Yuki888 [10]

Step-by-step explanation:

In the first part, he was travelling with twice the speed, or Vs, for distance

48 - d, for 2 hours.

speed = distance/time

distance = speed * time

First part :

48 - d = 2V * 2

⇒d + 4V = 48  

Second part:

d = V * 2

⇒d = 2V  

Substitute 2s for d in equation 1.

2s + 4s = 48

6s = 48

s = 8

The speed in the second part is 8 mph.

<u>The speed in the first part is 2s = 2(8) = 16</u>

I hope this helps
