Question

In a span of 10 days, a presidential candidate is able to visit 20 different cities. Convert this rate into a unit rate of cities per day. Then use that unit rate to calculate how many cities the president can visit in 35 days.

A. 55 cities
B. 18 cities
C. 45 cities
D. 70 cities

Answer 1

10/20 = 1/2

1/2 visit per day

35 * 1/2 = 70

Answer: D. 70 cities

Answer 2

To find the unit rate we first need to divide 20 by 10 which equals 2. So 2 is now our unit rate. Then we need to see how many cities the president can visit in 35 days. To find this we need to multiply 2 by 35 which equals 70. 70 is our answer.
Answer: D. 70 cities
