Formula Used :
Distance = Speed * time
given : Speed 1 = 40 mph and time = 60 mins or 1 hour
Speed 2 = 70 mph and time = 30 mins or 1/2 hour
So, D1 = 40 * 1
D1 = 40 miles
D2 = 70 * 1/2
D2 = 35 miles
Total distance = D1 + D2
Total distance = (40 + 35 ) miles
Total distance = 75 miles
Thus, total distance covered is 75 miles
