Josie took a road trip. she drove for 45 minutes at 70 miles per hour. then she drove for 15 minutes at 20 miles per hour. how far did josie drive? round to the nearest mile. a 3450 miles b 150 miles c 90 miles d 58 miles

D . 58 miles

Step-by-step explanation:

In order to find the distance travelled (d) in each stage, we will use the following expression.

d = v × t

where,

v: speed

t: time

First stage

v = 70 mi/h

t = 45 min × (1 h / 60 min) = 0.75 h

d = v × t = 70 mi/h × 0.75 h = 53 mi

Second stage

v = 20 mi/h

t = 15 min × (1 h / 60 min) = 0.25 h

d = v × t = 20 mi/h × 0.25 h = 5.0 mi

The total distance tyraveled is 53 mi + 5.0 mi = 58 mi

i can answer this if i have the answer choices
