Final answer:
Kam takes 45 minutes to mow his lawn.
Step-by-step explanation:
To find out how long it takes Kam to mow his lawn, we need to compare it to Jada's time. We know that it takes Jada 1 1/2 hours to mow her lawn. It takes Kam half as long as Jada, so we can divide Jada's time by 2 to get Kam's time. Half of 1 1/2 hours is 3/4 hours or 45 minutes. Therefore, it takes Kam 45 minutes to mow his lawn.
