Question

The table shows the number of miles driven over time time 4,6,8,10 distance 232, 348, 464, 580

Express the relationship between distance and time and simplified form as a unit rate. Determine which statement correctly interprets this relationship

Answer 1

The distance covered per hour are as follows:
4 to 6: 348 - 232 = 116 ÷ 2 hours = 58
6 to 8: 464 - 348 = 116 ÷ 2 hours = 58
8 to 10: 580 - 464 = 116 ÷ 2 hours = 58.

We see that the vehicle covers 58 miles every hour. Therefore, the relationship between distance and time is 58 miles per hour. Written as an expression:
distance = 58miles/hour,
or
d = 58t
where d is distance in miles and t is time
