Question

Franny took a road trip to her grandmother’s house. She drove at a constant speed of 60 miles per hour for 2 hours. She took a break and then finished the rest of her trip driving at a constant speed of 50 miles per hour for 2 hours. What was the total distance of Franny’s trip?

Answer 1

220 miles.

Explanation:

Distance travelled = speed * time

Total distance travelled = 60 * 2 + 50*2

= 120 + 100

= 220 miles.

Answer 2

total distance = 220 miles

Explanation:

given data

speed v1 = 60 miles per hour

speed v2 = 50 miles per hour

time t = 2 hours

to find out

total distance of Franny’s trip

solution

we know distance = speed × time ...................1

so

distance d1 = 60 × 2 = 120 miles

and

distance d2 = 50 × 2 = 100 miles

so

total distance = d1 + d2

total distance = 120 + 100

total distance = 220 miles
