_____________

Step by step

4.
Solve for Daryl
8 miles /40 min = x miles / 120 min.
Find rate 8/40 = .2 miles per minute
.2 x 120 minutes = 24 miles in 120 minutes

Solve for Isabella
5 miles / 30 minutes = x miles / 120 minutes
Find rate 5/30 = 1/6 rate x 120 = 20 miles in 120 minutes

5.
5 ears corn for $2.00
Find rate $2.00/5 = .40 per ear

Multiply .40 x 9 ears = $3.60 for 9 ears

6.

4 oranges for 2.45
Find rate $2.45 / 4 = .6125 per orange

.6125 x 8 oranges = $4.90
.6125 x 12 oranges = $7.35
