Just answering for a task
Answer:
Step-by-step explanation:
B) the stone hits the water within the first 2 seconds. Because the stone drops at the speed of 88 feet/second, and 88 x 2 is 176. but the bridge is only 135 feet tall.
so,
88 feet/second
176 feet/2 seconds
135 feet means that it reached the river within 2 seconds. it reached the river in 1.545 seconds
The answer for 7 x 42 is 294.
Speed= distance divided by time. The answer is 30, and im assuming miles per hour. Hope this helps
