Question

Jake and Jacob are running in a relay race. Jake runs 100 meters in 8.5 seconds, and Jacob then runs the same distance in 7.74 seconds. Sum = 15 ones + ______ tenths + ______ hundredths = ______ ones + 2 tenths + 4 hundredths = ______ tens + ______ ones + ______ tenths + ______ hundredths. Together, they ran __________ seconds in the 100-meter relay race.

A) 7.4, 5.1, 4.06, 1, 5, 1.1, 6, 15.24 seconds
B) 7.4, 5.1, 4.06, 1, 5, 1.1, 6, 16.24 seconds
C) 8.5, 7.74, 1.24, 8, 0, 1.3, 1, 16.24 seconds
D) 8.5, 7.74, 1.24, 8, 0, 1.3, 1, 15.24 seconds

Answer 1

The sum of Jake and Jacob's times in the relay race is 16.24 seconds.

Step-by-step explanation:

To find the sum of the times it took for Jake and Jacob to run 100 meters in a relay race, we need to first add their individual times together. Jake ran 100 meters in 8.5 seconds, and Jacob ran the same distance in 7.74 seconds. Adding these two times gives us a total of 16.24 seconds.

To break it down into ones, tenths, and hundredths, we can write it as 16 ones + 2 tenths + 4 hundredths = 16.24 seconds. Therefore, the correct option is D) 8.5, 7.74, 1.24, 8, 0, 1.3, 1, 15.24 seconds.
