Question

Shelley is deep sea

diving. She traveled
60 ft below sea
level to see the
coral reef. If she
dove at a consistent
rate for 4 minutes,
how far did she
travel every minute?

Answer 1

15 ft/min

Explanation:

Let x be the unknown

Since,

4 mins = 60 ft

1 min = x

cross-multiply

4 × x = 60 × 1

4x = 60

Divide both sides by the coefficient of the unknown

4x/4 = 60/4

x = 15

Answer 2

15ft/min

Explanation:

Just divide 60 by 4 to find the average diving/per minute.
