Step-by-step explanation:
3/8 and in decimal form it is 0.375
Answer: 5.5hours
Step-by-step explanation:
Total distance = 226miles
Total time = 7 hours
Let b represent total time spent while walking.
Distance (walking) = 4b
Distance ( riding) = 40(7-b)
Total distance 226 = 4b + 40(7-b)
226 = 4b + 280 - 40b
226 = 280-36b
b = 54/36
b = 1.5hours
Amount of time spent walking = 1.5hours
Amount of time spent riding = 7-1.5 = 5.5hours
Amount of time spent on bicycle = 5.5hours
