Answer:

  1. 42 mph
  2. 126 mph

Step-by-step explanation:

It takes 2 hours for the second train to catch the first, so the first must have had a head start of (2 h)(84 mi/h) = 168 miles.

The first train achieved that head start in 4 hours, so its speed was ...

  (168 mi)/(4 h) = 42 mi/h

The second train was 84 mi/h faster so its speed was ...

  42 mi/h + 84 mi/h = 126 mi/h

___

The two trains met at a distance of 252 miles from Boston.

14 volunteers will not be able to help.

Step-by-step explanation:

According to given statement;

One booth requires 3 Volunteers.

No. of booths = 16

Given number of volunteers = 62

We will multiply total number of booths with 3 to find the number of volunteers required.

Volunteers required = No. of booths x 3

Volunteers required = 16*3\\

Volunteers required = 48

Subtract the required volunteers from total volunteers;

62-48=14

14 volunteers will not be able to help.
