First, we need to find the combined rocking rate of Mr. Gillespie and Mr. Matheson.
Combined rocking rate = Mr. Gillespie's rocking rate + Mr. Matheson's rocking rate
Combined rocking rate = 28 times/min + 32 times/min
Combined rocking rate = 60 times/min
Now we need to divide the total number of times they need to rock the chairs by their combined rocking rate to find out how many minutes it will take them together.
Total number of times to rock = 1,020 times
Combined rocking rate = 60 times/min
Minutes to rock 1,020 times = Total number of times to rock / Combined rocking rate
Minutes to rock 1,020 times = 1,020 times / 60 times/min
Minutes to rock 1,020 times = 17 minutes
Therefore, it will take Mr. Gillespie and Mr. Matheson 17 minutes to rock the chairs a combined total of 1,020 times.
even though mr gillespie is 89 years old and mr matheson is 92 years old, they still have jobs as product testers at high-back rocking chairs inc. If mr gillespie can rock a chair 28 times per minute, and mr matheson can rock a chair 32 times per minute, how many minutes will it tke the two of them together to rock chairs a combined total of 1,020 times?
