Explanation Given Information: The first bicyclist pedals at the rate of 40 miles in 3 hours and the other one pedals at the rate of 50 miles in 4 hours. Consider the fractions 40 miles 3 hours and 50 miles 4 hours . Find the LCM of both the denominators: L .C .M . ( 3 , 4 ) = 12 . Now, multiply both numerator and denominator by 4 for the first fraction. 40 miles 3 hours = 40 × 4 miles 3 × 4 hours = 160 miles 12 hours Again, multiply both numerator and denominator by 3 for the second fraction
