This is how you solve it; but first of all convert the percent into a decimal;55%= 0.55
0.55x = 164 (divide by 0.55 on both sides)
x = 164/0.55
x = 298.18 (rounded to the nearest hundredth)
so 164 is 55% of 298.18(rounded)
Distance÷time
440÷8= 55
Therefore he needs to drive at the speed of 55 miles/hour
310 / 75-5 = 4.42 or 4.4 hours. Let me know if you have any other questions.
