Answer:

About 1.5799 seconds.

Explanation:

Since you know how high the egg is from the ground, you can simply plug it into d.
10=-16t^2-7t+61, which simplifies to
-16t^2-7t+51=0. Now you can just treat this as a quadratic equation to find that t is about 1.5799 seconds. PM me if you have more questions!
