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
