Answer:
5 5/8 miles per hour
Step-by-step explanation:
Martin can run 3 ¾ miles in 2/3 of an hour. Write a unit rate to describe the situation and explain the context.
We are asked to write the unit rate , this means we are to find out how many miles he can run per hour
Hence,
2/3 hour = 3 3/4 miles
1 hour = x
Cross Multiply
2/3 hour × x = 3 3/4 miles × 1 hour
x = 3 3/4 miles × 1 hour/ 2/3 hour
x = 3 3/4 ÷ 2/3
x = 15/4 ÷ 2/3
x = 15/4 × 3/2
x = 45/8
x = 5 5/8 miles per hour

Answer:
10 visits
Step-by-step explanation:
According to the scenario, calculation of the given data are as follows,
Rewards for signing up = 80 points
Reward per visit = 2.5 points
Total points needed = 105
Let, number of visits = x
So, we can calculate number of visits by using following formula,
80 + (2.5 × X) = 105
2.5X = 105 - 80
2.5X = 25
X = 25 ÷ 2.5
X = 10 visits.
Hence, Olivia needs to make 10 visits in order to earn a free movie ticket.
