Answer:
I am pretty sure it is 22m
Step-by-step explanation:
minus 2
3/5 is equal to 6/10 - always find a common denominator
So then you can easily add 1/10+6/10 which equals 7/10
The total length of Jiamin's trip was
distance = speed × time
distance = (52 mi/h) × (5 h) = 260 mi
The distance Jiamin traveled in her first 2 hours was
distance = (50 mi/h) × (2 h) = 100 mi
That means she traveled the last (260 -100) mi = 160 mi in the remaining 3 hours. Her average speed for that portion of the trip was
speed = distance / time
speed = (160 mi) / (3 h) = (160/3) mi/h ≈ 53 1/3 mi/h
Jiamin's average speed for the last 3 hours of her trip was 53 1/3 mi/h.
