To find the rate in miles per hour, divide the miles by the hours. (1 1/2 miles)/(3/5 hour) = = 3/2 miles * (5/3 hour) = 5/2 mph = 2 1/2 mph Her walking rate is 2 1/2 mph. (4 1/2 miles) / ( 2 1/2 mph) = = 9/2 miles / (5/2 mph) = 9/2 * 2/5 hours = 9/5 hours = 1 4/5 hours From 9:00 a.m. to 11 a.m., she has 2 hours, but she only needs 1 4/5 hours to walk, so she will make it to work on time.
You need to divide the 3 blocks of clay by the 4 friends. 3 goes in the dividend and the 4 is outside. 3 divided by 4 is equal to 0.75 or 3/4, so each friend gets 0.75 or 3/4 clay
