Answer:
Cesar goes 1 2\3 miles in an hour
Bella goes 1 1\3 miles in an hour
Cesar is hiking faster
Step-by-step explanation:
Cesar: you half 3 1\3 because you need to half the time of 2 hours to determine how far he goes in an hour. 3 1\3 halved is 1 2\3
Bella: You must multiply 1\3 4 times in order to get the 1\4 hour to a whole hour. 1\3 4 times is 1 1\3.
Speed: Cesar goes 1 2\3 mph while Bella goes only 1 1\3 therefore Cesar is going faster

Answer: the bridge is 11.025 m high
Step-by-step explanation:
Given that;
Time taken to hit the water t = 1.5 sec
height of bridge = ?
lets take a look at the equation of motion;
y(t) = y₀ + (1/2)at²
with initial velocity zero and we know that acceleration due to gravidity is 9.8m/s
we substitute
y(t) = (1/2)gt² = (1/2) × 9.8 × (1.5)²
y(t) = (1/2)gt² = (1/2) × 9.8 × (1.5)²
y(1.5) = 11.025 m
Therefore, the bridge is 11.025 m high
