Hey You!
The two are related because they both use the same three numbers. For example:
6 × 3 = 18 3 × 6 = 18
Or,
18 ÷ 3 = 6 18 ÷ 6 = 3
Answer:
38.60 mph
Step-by-step explanation:
Average speed = total distance / total time
44 mph = (70 mi + 60 mi) / t
t = 2.95 hr
The time spent during the first 70 miles is:
d = rt
70 mi = (50 mph) t
t = 1.4 hr
So the time spent during the last 60 miles is:
t = 2.95 hr − 1.4 hr
t = 1.55 hr
So the average speed during the last 60 miles is:
d = rt
60 mi = r (1.55 hr)
r = 38.60 mph
Answer:
Its 22
Step-by-step explanation:
